Norman E. Rosenthal

Norman E. Rosenthal is an American author, psychiatrist and scientist who first described seasonal affective disorder (SAD), and developed light therapy as a treatment.

Rosenthal was born and educated in South Africa but moved to the United States to complete his medical training. He established a private practice and conducted research at the National Institute of Mental Health (NIMH) as a researcher and senior researcher for more than twenty years. It was here that he studied disorders of mood, sleep, and biological rhythms and was the first psychiatrist to describe and diagnose seasonal affective disorder (SAD).

Rosenthal's research with SAD led him to write ''Defeating SAD,'' ''Winter Blues'' and two other books on the topic. Rosenthal has written two books on the Transcendental Meditation technique (''Transcendence'' and ''Super Mind''). He researched its potential application on patients with posttraumatic stress disorder (PTSD). He has also written a memoir (''The Gift of Adversity'') and a book on therapeutic effects of poetry (''Poetry RX''). In total, he has written eleven books and published over 300 scholarly papers.
